This summer the first Britishgrown edamame crop arrives in supermarkets.

Maintaining blood sugar levels, even in the absence of disease, may be an important strategy for preserving cognitive health, suggests a new study. The findings suggest that exercising to improve blood sugar levels could be a way for some people to stave off the normal cognitive decline that comes with age.

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

Long-term memory formation in honeybees is instigated by a calcium ion cascade. Researchers have shown that calcium acts as a switch between short- and long-term storage of learned information.

Researchers have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium and pave the way for new applications, including the possible use of A. vinelandii for the production of other proteins.

Changes in ocean chemistry -- a consequence of increased carbon dioxide emissions from human industrial activity -- could cause US shellfish revenues to drop significantly in the next 50 years, according to a new study.

Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life, report the authors of a new study. The culprit is atmospheric carbon dioxide, which even in a cooler globe will continue to be absorbed by seawater, creating acidic conditions.

In revisiting a chemical reaction that's been in the literature for several decades and adding a new wrinkle of their own, researchers have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it can be effectively industrialized, could allow many of today's petrochemical products, including plastics, to instead be made from biomass.

Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these "trans fats" gum up the cellular machinery that keeps blood moving through arteries and veins.

Because peak bone mass is not achieved until the third decade of life, it is particularly important for young adults to consume adequate amounts of calcium, protein and vitamin D found in dairy products to support health and prevent osteoporosis later in life. Researchers now report that young people actually reduce their intake of calcium and dairy products as they enter their twenties.

By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, geochemists have produced the first picture of how certain forms of iron were initially distributed in the solid Earth.

Researchers have made use of cryo-electron microscopy to show the exact process of enzyme activation. Pandinus imperator, the emperor scorpion, is not only popular as a pet, but is also of interest for research purposes. The reason for this is its blue blood, which transports oxygen and distributes it throughout the body.

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere will disappear; the oceans will evaporate; and all living things will disappear. Or maybe not quite so soon, say researchers who've found a mechanism that doubles the future lifespan of the biosphere -- and increases the chance advanced life will be found elsewhere in the universe.

An obscure species of beetle has shown how brilliant white paper could be produced in a completely new way. Researchers have taken inspiration from the shell of the Cyphochilus beetle to understand how to produce a new kind of white coating for paper.

Mexico's most famous drink comes in all shapes and sizes.

This study extends the existing literature by finding a strong association between low omega--3 fatty acids and depression in outpatients with stable coronary heart disease, a population distinct from sicker, hospitalized patients with acute coronary syndrome.
